January is Glaucoma Awareness month in the United States. Glaucoma is damage to the optic nerve, the part of the eye that brings vision information from the eye to the brain. It is usually, but not always associated with high eye pressure. The normal eye pressure is 11-21. Some people who have very high pressure will never develop Glaucoma, but unfortunately some people with "normal" pressure will develop all of the vision problems associated with the disease.
Every person should have a complete eye exam that includes a dilated pupil examination of the optic nerve. If there is high pressure or any question of abnormalities you may be asked to under further testing. Be aware of Glaucoma, this month and every month!
